Increased oil prices reduce almost everyone’s disposal income (it acts as a tax).

It does not act as a tax. A tax moves money from the citizen to the government which the government then (ostensibly) uses within the domestic economy. A high oil price (for an importer) moves money from within the domestic economy to an external economy. Since our economy is measured by how much money is moving around within it, moving money outside of the economy is bad for the economy.

Jim,

Thx for the more precise formulation. (slight populistic use of a picture from my side)

For an oil importer I agree, increasing oil prices will move and increased amount of money out of the economy.

My prime intention was however to draw attention to that there must (as of now) be a limit to how high oil prices will go before it starts to affect demand.

Looking at EIA data for total petroleum products consumption it looks as this zone is being entered now, looking and the increasing number of airlines reporting cutbacks and reduction in flights, the present run up in oil prices have already stated to take some effect on demand (consumption). And there is probably more in the pipeline.

I would expect there to be a timelag from the run up in prices until it turns up in reduced demand.
